From Mary Mapes' information for the show:
The outside panel CBS brought into to get to the bottom of the so-called Rathergate mess says. I recently re-examined the panels report after a source, Deep Throat style, told me to Go to page 130. When I did, heres the startling piece of information I found:
Mapes had information prior to the airing of the September 8  Segment that President Bush, while in the TexANG [Texas Air National Guard] did volunteer for service in Vietnam but was turned down in favor of more experienced pilots. For example, a flight instructor who served in the TexANG with Lieutenant Bush advised Mapes in 1999 that Lieutenant Bush did want to go to Vietnam but others went first. Similarly, several others advised Mapes in 1999, and again in 2004 before September 8, that Lieutenant Bush had volunteered to go to Vietnam but did not have enough flight hours to qualify.
